The present invention has relation to windows, and it is designed andcalculated to ro= tate the sash vertically; and it consists in thedifferent parts and combination of parts hereinafter describechandparticularly pointed out in the claims.

Similar numerals of reference indicate cori responding parts in all thefigures of the draw ings.

In the accompanying drawings, 1 represents the window frame or case,which is constructed in the ordinary manner, reference being bad to theproper attachment and arrangement of the different parts belongingthereto.

To the lower sill 2 is connected in any convenient and Well-known mannerthe supplemental base-strip or sill 3, which is formed of a length tocorrespond with the window, and its upper face is provided with thebeads or ribs 4 and the groove 5, said ribs and grooves being locatedand arranged substantially as shown in the drawings, and as shown theyare each provided with the inclined faces 6, said inclined faces beingso formed that they will present plain or smooth surfaces and are soformed for the purpose hereinafter described.

To the lower base-strip or sill is securely attached by means ofsuitable screws or their equivalents the base-plate 7, which base-plateis provided upon its top or upper side with the inclined faces 8, saidinclined faces being located substantially as shown in Fig. 8.

Upon the upper side of base-plate 7 is lo= cated the lifting-lever 9,the connected end of which is provided with the disk 10, said disk beingprovided upon its bottom or under side with the inclined faces 11, saidinclined facescorresponding in shape and pitch with the inclined faces8, formed upon the baseplate 7 For the purpose of providing a means forholding the lifting-lever proper in proper relative position withreference to the base-plate '7 it sbottom or under side is provided withthe hollow flange 12, said flange being seated in the aperture 13.

Upon the top or upper side of the disk 10 is located the friction plateor disk 14;, and for the purpose of preventing said friction-plate fromrotating with the lever 9 it is provided upon its bottom or under sidewith the downward-extending flange 15, which flange is pro vided withthe open recess 16, said recess being for the purpose of receiving thelug 17, formed upon and preferably integralwith the base-plate 7.

To the bottom or under side of the lower sash-rail 18 is connected theplate 1;), which plate is provided with the lug or bearing 20, saidbearing being so located that it will be entered through the opening 21in the frictionplate 14 and into the Opening 22, formed in the camportion 10 of the lever 9, said parts being located and arranged asillustrated in Fig. 11 when properly assembled and the window-sashproper and its glass operated, as hereinafter described.

To the top sash-rail 23 is connected the follower 24, to the top orupper side of which follower is connected the center plate 25, whichcenter plate is provided with the hollow lug 26, which hollow lug isseated into the follower 24, and for the purpose of providing abearing-point for the window-sash to turn upon at its upper end the hub27 is provided, which hub is placed through the hollow thimble 26 andseated into the upper sash-rail 23, and for the purpose of assisting inbringing the follower 24 down upon the upper edge of the upper sash-rail23 when the window proper is brought into a closed position, asillustrated in Fig. 1, the spring 28 is provided, which spring islocated around the hub 27, as illustrated in Fig. 12.

For the purpose of assisting in holding the follower in proper positionduring the time the window-sash is turned upoh its pivotal points thethimbles 29 are provided, which thimbles are located in the follower 24,the lower or headed ends of said thimbles being located in the apertures30, by which arrangement the follower is free to move up and down withthe up-and-down movement of the upper sash-rail 23.

It will be understood that screws such as 3l'and 32 are to be employedto connect the different parts together.

For the purpose of preventing any tilting movement of the follower 24the upper side of said follower is provided with the springs 33, whichsprings are located in the grooves 34, formed in the upper face of thefollower, and the inner ends of said springs securely connected to thefollower. The springs 33 are so formed that they will have a tendency atall times to force the follower toward the upper sash-rail 23 by reasonof their upper faces pressing or hearing against the upper bar of theframe 1.

When the window proper is in its normal position, as illustrated in Fig.1, the lever 9 is in the position illustrated in said figure. When it isdesired to lift the window proper vertically, the lever 9 is broughtinto the position illustated in the dotted lines, Fig. 1, the movementof which lever rotates the disk 10, the inclined surfaces or faces 11riding upon the inclined faces 8 of the base-plate 7, at which time theweight of the window proper is removed from the supplemental sill orstrip 3 and the follower 24 is forced upward toward the top rail of theframe 1 a distance equal to the elevation given to the window 1. Afterthe lever 9 has been brought into the position illustrated in the dottedlines the window proper is free to turn upon its bearing-points at itstop and bottom. As the window proper is turned the rib 35, formed uponthe top or upper face of the upper sash-rail 23, will be moved out ofthe groove 36, formed in the bottom of the follower 24, and in orderthat the rotary movement of the window will be easy the rib 36 isprovidod with the straight inclined ledges 37, and in order to provide aclose connection between the follower 24 and the upper sash-rail 23 theedges of said sashrail are provided with the ribs or beads 38, saidbeads being seated in the grooved edges 39 of the follower 24, saidbeads 38 and grooves 39 being provided with abutting edges 40. It willbe understood that as the window is turned upon its bearing-points thefollower 24 will be lifted a short distance by reason of the ribsprovided with the inclined edges riding upon the inclined edges formedupon the follower. tVhen the window is brought into its normal position,the springs 28 and 33 are released, or, in otherwords, their force willcause the follower to be seated snugly upon the top edge of the uppersash-rail 23.

tance to entirely separate the lower sill 3 from the lower sash-rail.

For the purpose of causing the hub 27 to turn with the window proper itsbottom or lower end is provided with the teeth 41, which teeth areseated into the upper sash-rail 23.

It will be understood that by providing the inclined edges the variousbeads and grooves formed upon the follower, upper sash-rail, lowersash-rail, and supplemental sill said parts can be easily detached anddisplaced without any stubborn resistance, such as is common to oppositeconcave and convex surfaces. It will also be understood that byproviding a bead and groove in the center of the follower and uppersash-rail, the lower sash-rail, and supplemental sill and formingadditional beads and grooves upon the opposite sides of the center beadsand grooves there can be no rocking or longitudinal tilting movement ofthe follower and at the same time providing a closer fit between thebottom and lower ends of the window proper.

For the purpose of making a solid joint for the upper bearing the spring28'is formed of one convolution, so'that when it is compressed the endswill come opposite each other, thereby forming a washer.
